FREDERIC A. DELANO, OF CHICAGO, ILLINOIS, ASSIGNOR OF TWO-THIRDS TO FRANK H. CLARK AND ROBERT D. SMITH, OF CHICAGO, ILLINOIS.

CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 759,970, dated'May 17, 1904. Application filed January 2, 1902. Serial No. 38,11i. (No model.)

To all whom it may concern.-

Be it known that I, FEEDERIO A. DELANo, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the 1 following, taken in connection with the accompanylng drawings, is a specification.

This invention relates to doors particularly adapted for use in cars engaged in carrying grain or other like materials, and has for its object the provision of a door of such character which, although hung upon the inside can be opened as to its lower part outwardly, and then moved out of the way with a minimum of trouble and so as to permit the rapid unloading of the contents of the car without interference from the door or any portion thereof.

In carrying out my invention I provide a construction which I have illustrated in preferred form in the accompanying drawings in which Figure 1 is an inside sectional view of a car showing my improved door applied thereto;

Figure 2 is a vertical section indicating the construction of the several parts, and

Figure 3 is an outside view of a portion of a car with my door applied thereto and in closed position.

Over the door opening 4 I have shown a supporting rail 5 of usual construction located upon the inside of the car, and carrying the hangers 6 which may be of any preferred type by which are suspended the two opposite sides of my door which consists primarily of an upper frame and panel 15, 7 to which is fastened by the hinges 8 a lower frame 9 provided with another panel or section 10 hung upon hinges 11 so as to be capable of opening outwardly, the panel 10 being construted out when the outer or weather door 13 is slid open as shown in Figure 3.

The operation of my invention is as follows: Assuming the parts to be in the positions shown in the several views, and the car to be loaded with grain, if it be desired to unload the contents of the car the outer door-13 is moved back out of the way as shown in Figure 3, and the sliding bolts 12 are loosened when the pressure of the grain upon theinside'will push the lower panel 10 outwardly into approximately the position shown by the dotted lines 14 in Figure 2,permitting that portion of the grain which is immediately within the door to readily discharge orbe taken out. As soon as thisis done the panel lOis returned to position and the bolts 12 secured to frame 9 to hold it so, after which the lower frame 9 is swung upwardly upon the hinges 8 and the entire door including the two panels and the frame 9 is then slid laterally along the track 5 as will be clear from an examination of Figure 1, until it is clear of the door opening 4, the grain being moved away from the sides of the car a suflicient amount to permit this to be done. To close the door the reverse operation takes place as is obvious withoutfur-.

ther description.

While I prefer to construct the door with the frame 9 hinged relatively to the upper frame 15 and panel 7 it is obvious that such pivotalconnection between the upper portion and the frame 9 might be dispensed with, the outwardly openable lower panel still being employed in conjunction with my improved construction of inside hung door, whereby at least some of the advantages of my improvement would be obtained, and I therefore desire it to be understood that I regard such construction as clearly within the scope of my generic claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A laterally sliding car door comprising a main section and a depending hinged frame abutting against the inside of the door opening, a panel hinged within said lower hinged frame to open outward, being smaller than the door opening and abutting against said frame.

2. Alaterally sliding car door comprising a two part frame one part hinged to the other and an outward opening panel in the lower part of said hinged frame, the lower frame abutting against the sides of the car and the panel against the swinging frame.

3. A laterally sliding car door comprising an upper panel, a frame larger than the door opening made in two sections hinged together, a second panel hinged within the lower section of the frame openable outward through the frame andthe door, and inwardly abutting against the said lower hinged frame section.

4. A car door comprising an upper frame and panel larger than the door opening hung insidethe same, a lower frame larger than the door opening hingedtothe upper frame to open inward, a panel within said lower frame hinged 2 ing the said panel in place.
